'Annllcatiouflledhlarcli],1907. Serial No. 361178r p To all whom it may concern:

Be it known that I, \VILLIS l. Mittnn, a citizen ol' the United States, residing at'tjleveland, in the county of Cuyahoga and State of Ohio, have invont'cd certain new and useful improvements in ltlectrioally-Operuted Vibrators; and i do deelare'that the following is a full clear, and exact descriptionoi the invention, which will enable others skilled in the art to which it appertaius to make and use the same.

lily invention relates to-au electrically operated I vibrator, and the invention cimsists in the construction and arrangementoi parts, substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspet'tive view oi my new and improved ibmlor. Fig. 2 is a Vertical cross section theftof at right angles toils p axi and Fig, :3 is a cross section at right angles to Fig. 2, both oi these views being eorrespondingl I \\'hut 1 claim is:

united on the plane 01' the motor axis and separably,

secured together. The shaft ii is supported at its end in hearings within the casing andlnotor U is lined thereon and proi'idedwith lields 1*, eonnnutatorr and suitable operating and electrical connections prelerably through handle it. Said handle is supported through a. hole in the casing by a spring It insideand oi sullieient strength but also with sullieient resilient-y to praetioally absorb the \llll'lllltlllS so far as lhe hand is eonttel'ned. Said handle. is at rightaugles to the motor a-itiso'r shalt.

The weight Dis preferably ul substantially crescent shape, or approximately in side elevation and is hungun shalt B so as toslido to and Ironi the some within limitsaeeording, as greater or less vibratory aetion, or emph'asis oi action, is-wanted, and to this end 1 provide the said weight with a double sided triangular shaped support :1 having straight edges 2 eomerging toward the weight and cross portion ii connecting the deflected ends of said side edges and engaged centrally with the weight by means of a screw 4. Shaft U passes between the opposite sides 2 of said support (I, and screw 4 is projeel etl through shaft B and slidsble therein, and serves to operatively engage the weight with the shaft.

Sleeves J' are splined or otherwise slidably mounted on shaft 15 and have inner beveled l'aees oi the same angle as inclined edges 2 against which they hear, and

said sleeves are engaged at their outer portions about shalt ll by clamping anus l1 buid arms are pivot-ally united-and adapted to operhte after the manner of pincvrs or tongs by a joint pivot 5 on logs or ears 6 on i the inside ol-the casing end with their outer ends eiti tending and spread outsidethew-usingond connected by a screw 8 This enahles me topress the sliding sleeves J inward more or less and thereby erowd'the counterweight correspondingly hiward'toward shalt B and thus lessen its throw and the vibratory action. 5 Applieator l) is mounted one band N rotarili' adjustable about easing A and is locked in adjustment by pin or bolt 10 from the inside of the easing'and supported by spring lllaud controlled by linger grip 14'. v Said bolt lakes into holes la; in the band, audit will be seen that said band bolts the shell or sphere upon the axis of shaltll, so that as the applicator is shiited around more or less toward said shat'tthe vibratory arti'ou therein is modified, and there is considerably less of the pounding effect than whenasshown.

I. In t'llt'll'itilll) actuated vibrators, aspllericnl easing, a shalt iuouutrd eoutrally in said casing, an ett-et'ric motor ll[ml1 N:ti(l shall within the casing and i1 weight eceentrle mounted on sold shaft hctwrt-n the ends thereot' in said casing and a handle mounted on siiidxaslug.
